+### Applying Salt states
+
+A ````pwd`/srv/salt``` directory has been created during the startup of the `saltmaster` container. Place your SLS state definition in it.
+
+An example follows:
+
+```bash
+% cat srv/salt/tmux.sls
+```
+
+```yaml
+tmux:
+  pkg.installed
+```
+
+Now you can apply the state file to your minions:
+
+```bash
+docker exec saltmaster /bin/sh -c "salt '*' state.apply tmux"
+```
+
+```

 ## Caveats and security
 
 * `saltstack-master` exposes port `8000/tcp` (**NO SSL**) in order to consume `salt-api` via its HTTP interface.
